ABSTRACT:
A means for removal of snow and/or ice from a road or other equivalent area, meant to be attached to a work machine, said means comprising a helical cutter (10) disposed substantially transversally to the direction of travel of the work machine, a drive means (11) for rotating the cutter about its central axis (12), and members (6,7,8) for collecting the material detached by the cutter (10) and for their removal from the ground and transportation onto a load platform (9). The object is to eliminate the drawback encountered in means of this kind that it is not possible with them to remove the snow and ice simultaneously from the carriage-way and pavements and from behind traffis signs, posts and other similar obstacles.
As taught by the invention, the means comprises a rotating side cutter (10) provided with controls (13,13') for displacing the side cutter in the height direction and in the direction of its axis, and preferably an end cutter (30) which has been mounted crosswise with the cutter (10) preferably on the outer end thereof and has been provided with a drive means (31) for rotating the cutter about its central axis (32). The end cutter has been disposed preferably pivotally with reference to the helical cutter (10) and provided with a force means (34) so that the end cutter is turnable up and into horizontal position.
